The utility model discloses a kind of commercial car the OBD diagnostic socket assemblies with secondary locking are plugged with resistance to, belong to Automobile Failure Diagnosis Technology field, including socket, square opening shape column terminal, terminal position groove, secondary locking system, drawing and pulling type locking device and protecting crust；Square opening shape column terminal is located in the jack of hub tail, square opening shape column terminal carries out locked fixation by terminal position groove, hub tail is provided with secondary locking system, is securely fixed in socket, socket is installed in protecting crust, the afterbody of protecting crust is equipped with drawing and pulling type locking device, is easy to the dismounting and fixation of socket.Existing Y types terminal is changed to square opening shape column terminal by the socket assembly, and hub tail sets secondary locking system, prevents terminal from passively exiting, while the installation and maintenance to terminal more facilitate, reliably；Protecting crust afterbody sets protecting crust drawing and pulling type locking device, and the assembling to diagnostic socket more facilitates with safeguarding and using, and prevents socket from being exited under external force, reliability is improved.
Description
Technical field
The utility model belongs to Automobile Failure Diagnosis Technology field, and in particular to a kind of commercial car is with resistance to plug with secondary lock
OBD diagnostic socket assemblies only.
Background technology
Commercial-vehicle cab Type B OBD diagnostic socket assemblies, are to accept connecing of being connected with computer diagnostic instrument of Engine ECU
Mouthful and passage, be responsible for communication between Engine ECU and computer diagnostic instrument and fault diagnosis, once occur loose contact or other
Problem, will cause the communication disruption between diagnostic equipment and Engine ECU, and Engine ECU data can not be read, and failure code can not
The problems such as identification judges and demarcation can not be carried out.
At present, the socket assembly used is import connector product, and its connector internal terminal is y-type structure (Fig. 1), right
The terminal sizes of spigot diagnostic plug require high, require neat to the arrangement of spigot terminal, slightly off-center, in swapping process
Easily cause diagnostic socket terminal strip easy damaged, it is serious it is even direct terminal is exited, or the failure such as loose contact, meanwhile,
The outlet of former female terminal is strip row, and plug end, which is not easy to find hole position accurately, is docked, and is overexerted and is easily caused socket assembly
And terminal is damaged.
Utility model content
The purpose of this utility model is to provide a kind of installed in commercial-vehicle cab Type B OBD diagnostic socket assemblies, solution
Certainly socket of the prior art plug number of times is few, terminal is fragile, to inserting difficult the problems such as, be easier plug, plug number of times
More, reliability is higher, and with secondary locking system, installs, safeguards the more low advantage of more convenient, maintenance cost.
A kind of commercial car resistance to OBD diagnostic socket assembly of the plug with secondary locking, including socket, square opening shape column terminal
1st, terminal position groove 2, secondary locking system 4, drawing and pulling type locking device 5 and protecting crust 6；Square opening shape column terminal 1 is located at socket
In the jack of afterbody, square opening shape column terminal 1 carries out locked fixation by terminal position groove 2, and hub tail is provided with secondary lock
Locking apparatus 4, it is securely fixed in socket, socket is installed in protecting crust 6, the afterbody of protecting crust 6 is equipped with the locked dress of drawing and pulling type
5 are put, is easy to the dismounting and fixation of socket.
Further, the socket assembly also includes positioning baffle 3, can prevent other kinds of diagnostic plug wrong plug.
Compared with prior art, the utility model has the following advantages that：
1st, existing Y types terminal is changed to inside square opening shape column terminal, terminal carry shell fragment, it is ensured that terminal can when injecting
It is abutted against tactile, relaxes while requiring relative to insertion terminal arrangement, terminal is hardly damaged during pushing and plugging, reliability is improved, and is met
ISO 15031-3-2004 requirement, while the maintenance of terminal is more facilitated；
2nd, secondary locking system is set in hub tail, prevents terminal from passively exiting, while installation and maintenance to terminal
More facilitate, reliably；
3rd, protecting crust drawing and pulling type locking device is set in protecting crust afterbody, the assembling and maintenance and use to diagnostic socket are more
Plus conveniently, preventing socket from being exited under external force, reliability is improved；
4th, diagnostic socket carry protecting crust, diagnostic socket is played a part of it is dust-proof, protection, while play decoration, it is attractive in appearance
Effect.

Embodiment
The technical solution of the utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1
A kind of commercial car resistance to OBD diagnostic socket assembly of the plug with secondary locking, including socket, square opening shape cylindrical end
Son 1, terminal position groove 2, secondary locking system 4, drawing and pulling type locking device 5 and protecting crust 6；Square opening shape column terminal 1, which is located at, to be inserted
In the jack of seat afterbody, square opening shape column terminal 1 carries out locked fixation by terminal position groove 2, and hub tail is provided with secondary
Locking system 4, it is securely fixed in socket, socket is installed in protecting crust 6, the afterbody of protecting crust 6 is locked equipped with drawing and pulling type
Device 5, is easy to the dismounting and fixation of socket.
Further, the socket assembly also includes positioning baffle 3, can prevent other kinds of diagnostic plug wrong plug.
When needing to use diagnostic socket, first open the outer protecting crust of OBD diagnostic sockets, computer diagnostic instrument plug according to calmly
In position direction insertion diagnostic socket, after pushing hard in place, the blade terminal of diagnostic plug and the square opening shape column terminal of this socket
Reliable contacts are carried out, connection purpose is reached.
When needing dismounting diagnostic socket, the protecting crust drawing and pulling type locking device 5 of protecting crust afterbody outside diagnostic socket is drawn
After going out, you can socket is extracted out from protecting crust；Needed during loading after first the protecting crust drawing and pulling type locking device 5 of afterbody is pulled out,
Socket is pushed into protecting crust again, then the protecting crust drawing and pulling type locking device 5 of afterbody is pushed into protecting crust, i.e., diagnostic socket
It is locked.
